what motor? how good is a 413?

[Harper]

ok i have a few questions on 383's, 413's, and 440's.
What are the differences? other than cubic inches of course.
will the heads and intakes interchange?
would you guys say a 383 would be nearly as powerful as a 440?
what about a 413 compared to a 440?

a buddy and myself are building two cruisers, both will be big block mopars, mine is a 68 with i believe a 440. His he has not purchased yet. We want them to be reasonably fast, My list of future mods is listed below.
Hydraulic Roller cam and Lifters
Roller Rockers
4 barrel intake (4 barrel carb)
Electric Fans
larger aftermarket Wheels and Tires
Larger Dual Exhaust with X pipe and Flow Masters (love me some flow masters)

OK
here goes

ok have a few questions on 383's, 413's, and 440's.
What are the differences? other than cubic inches of course. RB vs LB
will the heads and intakes interchange? Yes and No
would you guys say a 383 would be nearly as powerful as a 440? Nearly = Yes
what about a 413 compared to a 440?[/QUOTE] depends 413 will cost a lot more to build than 440's if you need new pistons but they have the same stroke

 

[tallhair]

Also RB 383's from 58 if memory serves are RB's the rest are LBs

you left out some btw

. But I think your in the wrong place for what you have in mind, it seems. You won't get much support for big wheels and tacky modifications here. Good luck with your projects.

 

[1978 NYB]

B engine's 361, 383, 400 intakes interchange.

RB engine's 413, 426W, 440 intakes interchange.

Ditch the roller cam idea. You won't need it. The Chrysler lifters are large enough to use on a very high lift cam. Spend the money elsewhere.

More importantly, first figure out what engine you have.

 

[Big_John]

4 barrel intake (4 barrel carb)

Oh wait.... If you have a 2 barrel intake, you probably have a 383.

no not a bottom dragger or low rider car lol I mean a driver (I guess i should have been more clear).

i am not a beliver in "big Lift cams" the roller cam deal is for reduced friction and quick reving...

Oh wait.... If you have a 2 barrel intake, you probably have a 383.

it does have a 2V carb...that really kinda sucks, if it is...i was going for a 440

 

[detmatt]

Agreed, Ma Mopar didn't make a 440 with a 2bbl and I'm 97% sure the same can be said for the 413.

You will never feel the performance difference of a roller over a flat tappet in a C-body.
You're reading too many Mopar Performance articles.
Hate to pop your bubble. Sorry...

Best figure out what you have before you do anything else.

The roller cam will do nothing except empty your wallet. If you want a "quick reving" engine, walk away from this project. You build a big block Mopar for torque.... especially in a heavy C body. You have to have the mantra "it ain't a small block Chevy" when you are building these engines.

"it ain't a small block Chevy"

That's why mine isn't in a scrap yard.

The 413 is a great motor but is often forgotten in the world of high performance. But, as has been said, they are expensive to build. Since they are externally identical to a 440, all that can fit on a 400 will fit a 413. When looking for a core they are far cheaper to buy than a 440 too.

I by no means learned about a roller cam from reading a Mopar Performance Article, nor owning a Small block chevy. I learned it from having a 5.0 Mustang, and later building a Roller Cammed Ford 460 big block for a light weight mustang coupe.
oh i know its not a "dart" but just because it isn't doesnt mean you cant improve the performance with Roller Cam, roller lifters and roller rockers. Like i stated before, its going to be a driver. A car from the past to enjoy and have fun with. I probably wont build it like most ppl would. But then again i have been drag racing for 25 plus years, in that time i found a few things that also will work on a daily driver. A roller cam/lifers will be one of those improvements. why? i guess because I just dont like breaking in non roller cams/lifters lol, no really its that i cant stand the thought of all that friction on the cam with the non roller lifters I may have selective OCD haha

 

[saylor]

let me understand, because im a little slow, and i dont want to miss anything.

1.) you joined this site in 2012
2.) at some point you bought a '68 mopar
3.) you have 25 years drag racing experience
4.) you dont even know what motor is installed in your own car
5.) you came here asking opinion on mopar motors, and their configurations
6.) you blow off all advice, and just do your thing anyways, because you know more than we do

good luck with your mustang build.

try not to die -

400 is a B engine, the 413 is an RB.

There were 413-2 truck/RV and industrial applications.

 

[tallhair]

Matt is correct of course but i'm pretty sure that was just a typo

I think he intended to type " Since they are externally identical to a 440, all that can fit on a 440 will fit a 413 "

 

[Snotty]

400 is a B engine, the 413 is an RB.

My error in writing 400. Please note, I was talking about the 440 and 413.

a buddy and myself are building two cruisers, both will be big block mopars, mine is a 68 with i believe a 440. His he has not purchased yet. We want them to be reasonably fast, My list of future mods is listed below.
Hydraulic Roller cam and Lifters
Roller Rockers
4 barrel intake (4 barrel carb)
Electric Fans
larger aftermarket Wheels and Tires
Larger Dual Exhaust with X pipe and Flow Masters (love me some flow masters)

If you are doing a full rebuild, do some mega-research on stroker kits in 383/400 or the 440 blocks.
We don't know your budget or scope so further advice cannot be focused efficiently.

A roller cam in a BB Mopar was a $750 proposition last time I researched it, that $$ would be better spent elsewhere.

If a 413 is healthy it is worthwhile to modify, although the small bore (smaller than a 383) is a limit against valve size and breathing. However, Max Wedge 413s seemed to run hard, but everything on them was a package and probably not a streetable engine for a heavy C-body. The cross-ram and dual-quad 413s of 59-62 on the 300 Letter cars are worth review also, for those are heavy cars. Crossrams are very cost-prohibitive, but the DQ intakes are reasonably-priced (in comparison, anyway) - but even then, a proper single 4-barrel will work just as well.

If you want a C-body to be 'reasonably fast', then you need a either a well-sorted 440 or a B-block stroker at a minimum. Most 383 and 413 C-bodies are not terribly fast compared to modern cars such as VTEC Civics, V6 Mustangs and Camaros, etc. There are so many 280+ hp cars out there that a mild C-body cannot outperform.
